If you customize the tab bar removing the "new tab" button, and started to open many tabs, not blank tabs, when the number of tabs don`t fit on FF window (aka FF insert the scroll ">" button), tab bar animation begins a loop. It appears that the ">" buttons is inserted and removed continuously, making the entire tabs get large and small, in loop.
This happens almost all the time, but some times you need to load or reload the tabs (this changes the tabs width) to start the loop.


Reproducible: Always

Steps to Reproduce:
1.Remove the "new tab" button from the tab bar
2.Open many tabs (not blank tabs)
3.The animation loop beging
Actual Results:  
Animation loop on the tab bar

Expected Results:  
Tab bar with a lot off tabs opened with no loop

It's only happen with FF 4

I'm using beta 7 for a while now and this doesn't happen any more.
Beta 7 seems to resolved the animation problem.
I think this bug can be closed.
